One of the independents who helped to create the scheme, Rob Oakeshott, says the toxic nature of the politic debate is a significant threat to the scheme's future.

"Frankly it's going to come down to good Liberals either changing the policy position that the Liberal Party now holds, or changing the leader if they are not willing to change."

"The key to the success of this is getting confidence in the marketplace ... it all fails unless there are big bets made by big players, and they will only do that when there is confidence in the market and that will only happen when the politics settles down."
